What are electric actuators used for?
Typical applications of electric actuators In the food and beverage industry, for production of PET bottles, filling and labelling systems and robotic applications such as milking robots. They are used in materials handling for operations such as servo presses and clamping and widely used in the packaging sector.
What is an electric linear actuator?
Linear actuators are a type of actuator that convert rotational motion in motors into linear or straight push/pull movement. Linear actuators are ideal for all types of applications where tilting, lifting, pulling or pushing with pounds of force are required.
Which motor is used in electric actuator?
Electric actuators are a combination of a servo motor with worm gear to prevent reversal of drive direction by an unbalanced load. Generally, three-phase AC motors that deliver higher torque (ranging up to >80,000 NM) are deployed. However, single-phase AC or DC motors have also been used, but infrequently.
How do electrically actuated valves work?
Torque is the rotational force an actuator generates to close a rotational valve. Electric actuators can generate this force by transmitting it to the output shaft and then the valve stem. When pressure is applied to the valve stem, the valve’s orifice opens or closes.
What is the working principle of actuator?
What is the Working Principle of Electric Linear Actuators? The basic working principle of electric linear actuators is to convert the rotary motion into a linear motion. This conversion of motion is done with the help of a gearbox and a lead screw. These are the two most important electric linear actuator parts.
Is relay an actuator?
A relay is regarded as a binary actuator as it has two stable states. Relays are either energized and latched or de-energized and unlatched. Meanwhile, a motor is considered as a continuous actuator as it rotates through a full circle.
How are actuators powered?
They are powered using an electrical current and typically used within control systems. These types of actuators carry numerous benefits: they are simple to build or apply, carry minimal noise, and are cost and energy-efficient. Their downsides are that they are low speed and inappropriate for heavy loads.
What makes a good actuator?
An electric actuator’s best feature in comparison to the competing actuators is the flexibility of its motion control capabilities — they offer a large amount of control. Accuracy and repeatability levels are higher than for other actuator types.
What are the types of electric actuators?
Types of Electric Actuators
- Actuator.

Where is actuator used?
Industrial plants use actuators to operate valves, dampers, fluid couplings, and other devices used in industrial process control. The industrial actuator can use air, hydraulic fluid, or electricity for motive power.
